Title: Control apparatus incorporating a friction drive for a loading system for mine tubs and the like
Inventor: FOREMAN HARRY MAYNARD
IPC: B61J3/08
Filed: 1949-03-03
Abstract: 677,241. Apparatus for conveying from working face. NATIONAL COAL BOARD. April 3, 1950. [March 3, 1949] No. 5827/49. Class 78 (iv). [Also in Group XXIV] In loading system for mine tubs and the like, a drive is transmitted alternatively to two units by friction gearing. As applied to a coal mine a motor S is mounted on a frame 1 weighted at 2 and pivoted at 3 to a stationary frame 5. A friction roller S<SP>2</SP> on the motor shaft is located in, and may be brought into contact with the inner face of a hollow pulley G<SP>1</SP> on the gear box driving the scraper chain loading the coal. A motor P for moving the trucks into the loading position is similarly mounted and has a roller P<SP>2</SP> engageable with a hollow pulley GG<SP>4</SP>. The two pivoted motor frames 1 are interlinked and arranged to be tilted by a pedal 11 to bring either the roller S<SP>2</SP> or the roller <SP>p2</SP> into driving engagement with its respective pulley, so that the trucks are stationary while being loaded and, similarly, loading is stopped while the trucks are moved. The tilting of the motors may be effected automatically by the respective weights of a full and an empty truck. In a modification employing a single motor to drive alternatively two units, the motor carries at each end a friction roller within a driven pulley, the two pulleys being offset, and is pivotally mounted to bring either one or the other into driving engagement ; alternatively, the motor is stationary and each friction roller is carried by a swinging arm. In a further modification a single tiltable motor carries a friction roller engageable externally with either of two sideby-side driven pulleys. Where the motor is a steam or compressed air engine a control valve governing the engine speed may be incorporated.

Title: Improvements in or relating to the manufacture of coaxial conductor electric cables
Inventor: BEVERIDGE JOHN COLQUHOUN
IPC: H01B13/18

Abstract: 695,018. Cable making machine. STANDARD TELEPHONES & CABLES, Ltd. March 9, 1951 [March 10, 1950], No. 6072/50. Class 36. A machine for making a coaxial cable in which the conductors are spaced apart by insulating discs comprises a wheel 13 provided with a peripheral flange having a plurality of slots 15 extending through it, a device for feeding centrally apertured discs 2 into the slots from the inside of the flange, means for making radial slits in the discs, and means for applying the slit discs to the conductor 23 from the outside of the flange. The discs are fed from a supply hopper to shoot 11 in which they travel downwards under gravity to the inner side of the flange, which comprises a number of sections 14 separated by slots 15, and which is grooved on its outer surface. As a slot 15 passes under shoot 11 a disc falls into the slot and is then carried past knife 18 which projects into the groove on the flange, and slits the disc radially. Arcuate guide members 19, 20 are provided both inside and outside the flange to retain the discs in the slots 15, part of the outer guide 19 having a ridge 22 (Fig. 7) which forms a continuation of knife 18 and lies in the groove of the flange, thus holding the slit open as the disc travels round with the applicator wheel. The conductor 23 is moved tangentially across the topmost part of the wheel 13, so that it lies in the groove of the flange. Before the disc reaches the conductor 23 the ridge 22 is widened to wedge-shape, Fig. 7 (A-D) at the same time being tapered in the radial direction, allowing the conductor to enter the slit until it reaches the central aperture of the disc, when the slit closes, Fig. 7 (E). A tubular outer conductor (not shown) is finally applied to the insulated core 23. Specifications 458,772, 625,534 and 631,914 are referred to.

[Class 44.] Reversible rim locks, rim latches and the like have a removable and reversible fore-end plate F provided with lugs A, A<1> which enter the lock case to retain the plate in its correct position pending the fixing of the lock to the door. A spring C on the lug A helps to hold the plate, and the screws, which fix the lock, pass through holes in the lugs A, A<1>. The plate may be flanged to fit against the face or the top and bottom edges of the lock case. In a modification, each lug is formed as a thin tongue A2, Fig. 4, which engages in a socket D formed by bending the wall of the lock casing.

Abstract: 1338968 Communication system ROBERT BOSCH ELEKTRONIK GmbH 14 Feb 1972 [22 May 1971] 6725/72 Heading G4H In a communication system for vehicles (e.g. buses) equipped with a transmitter and a receiver and which are supervised and controlled from a central transmitting and receiving radio station by means of data messages D of equal length exchanged between vehicle and station, each data message D is composed of a start bit St and blocks BI 1 -BI 6  each containing the same number of bits. The message D is divided into two parts I, B; blocks BI 1 -BI 4  in part I contain digits Z 1 -Z 4  in BCD code together with parity bits P 1 -P 4 , whereas blocks BI 5 , BI 6  in part B contain digits Z 5 , Z 6  in 3-out-of-5 code. For the station-vehicle message, part I provides the address, digit Z 5  represents a request (e.g. for delivery of a report concerning location or occupancy) and digit Z 6  represents a command (go more quickly/slowly, await maintenance truck &c.). For the vehicle-station message, I contains the information requested by Z 5 , digit Z 5  indicates the type of report (location, occupancy &c.) and digit Z 6  indicates further information (e.g. repair truck to be sent). Data is evaluated in the station and a further message is sent to the same vehicle if required. Both messages being of equal length, a message may be transmitted on one channel while another is being received on a second. Both vehicle and station may contain shift registers to evaluate and deliver the messages; one shift register may be used to perform both functions.

The partial layer preferably borders immediately on the first layer and is at least 10% and at most 90% of the thickness of the second layer. The diffusion inhibitors preferably plug into lattice gaps in the partial layer and preferably comprise OH ions and/or bivalent cations (barium, calcium, beryllium). Trivalent ions (gallium, aluminium) may also be incoporated, the molar concentration of these being approximately twice the molar concentration of the bivalent ions. Alternatively, or as well as, small air bubbles may be used. A further layer 5 of finely-crystalline modifications of quartz, e.g. cristobalite may be provided on the outside. The tube 1 is continuously rotated while finely pulverized rock crystal is sprinkled thereon and fused by high output burners, so as to build up the layer 2 with the partial layer 3 adjacent the tube surface 4, the layer 3 being formed with air gaps by sprinkling more rock crystal than can be fused by the burners, and the additives are mixed with the rock crystals in this period only. The pure cristobalite is then finally added and fused (as in an oven) to preserve the final shape.

Relates to radio direction-finders in which the ratio of two signals A, B corresponds to angular position. According to the invention signals A+jB, A-jB are formed therefrom, are switched successively and cyclically (switching frequency f c ) to a limiting amplifier 14 which feeds a phase detector 17 which is supplied additionally with a second signal which is a function of at least one of A, B, and the output of the phase detector is, in synchronism with the switching, multiplied by + 1 and - 1. In one embodiment a delay line 110 (delay=1/(2f c )) and a 90 degree phase shifter 111 (the signals being at I.F.) are used in the path of the second signal. In one modification the second signal is A, Fig. 2 (not shown), and in another modification when signal A+jB is switched to amplifier 14 signal A - jB is switched to a further limiting amplifier (34), and vice-versa, in the second signal path, Fig. 3 (not shown). The effect of a parasitic phase shift is reduced. The invention may be applied to the direction-finding of a missile which carries a transmitter, Fig. 4 (not shown), an M.T.I. pulse radar, Fig. 5 (not shown) In a monopulse radar, signals A and B are the conventional sum and difference signals respectively.
